On motherboard's it's particularly the CMOS devices subject to static damage. All the amp parts we're working with aren't too sensative, relatively, but still there is a risk, if you knew what you were doing you could easily destroy these parts by shuffling around to build up a charge then zappin' a part against a grounded object.
If one doesn't want to go whole-hog and get mats and straps, etc, etc, at least you can have a grounded metal piece of equipment nearby and discharge yourself by touching it after walking around or large brushing-against-fabrics or desks or whatever. So, you were grounded and picked up an opamp, walked across the room and built-up a few thousand volts of charge... What to do? Do NOT put down the opamp "first". First use your other hand to touch a grounded object, preferribly also wherever you'll be placing that part, and once you are at same potential as the target area, THEN put the opamp (or whatever) in contact with it.
